THlLL-COUPLING.

SPECIFIGATION forming part of Letters Patent No. 286,123, dated October 2, 1883. Applicatirn filed July 31, 1883. (No model.)

To aZZ whom it may concern.-

Be it known that I, IRVING ELTING, of Poughkeepsie, in the county of Dutchess and State of New York, have invented a new and useful Improvement in Thill-Oouplings, (for which I have never obtained a patent in any country, and which has not been in public use or on sale in the United States for more than two years prior to the application in this country;) and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification. I

My invention relates to thillcouplings; and it consists of an improved construction and arrangeinent of the constituent parts, by means of which the absence of all noise from rattling is secured, in conjunction with the greatest ease of transfer from shafts to pole and vice versa, and the greatest simplicity of construe tion, the number of parts being reduced, to three.

The principal features of my device are, first, a thill-iron similar to that used in the old-fashioned bol.t-coupling, except that the eye islarger in diameter and contains a leather packing, which projects far enough 011 each side of the eye to admit of its being turned and litted against each side of the thill-iron, so as to prevent all rattling by lateral motion upon surfaces which, in most couplings, are entirely unprotected by packing; second, attached to the clip is a head, in the center of which and projecting inward horizontally parallel to the axle is a strong cylindrical spindle, about five eighths of an inch long, and into this, as far as the head-piece, is drilled a hole with thread, for the reception of the combined bolt, head, and nut hereinafter described, and the end of the spindle is beveled with a round bevel for about one-eighth of an inch, so that while the main surface of draft is straight (avoiding the sidewise tendency of what in one coupling is known as the conoidal -shaped lug) the thill-iron may be sprung into place upon the spindle without roughing the edge of the leather packing; third, a combined bolt, head, and

nut in one solid piece, which, when the thillirons have been sprung into place, may be screwed into the spindle firmly against the packed surface of the inside of the thill-iron. I do not limit myself to the use of this precise kind of packing; nor do I" limit this device to its employment as a thillrcoupling, as it maybination, as it is equally applicable wherever it is desirable to take from the bolt the cont-inual wear of a bearing-surface.

In the drawings, Figure l is a view in elevation of a thill-conpling constructed accord ing to my invention. 3 is a plan view of the same, and Fig. 6 is a transverse sectional view of the same. Fig. 2 is a View in elevavation of the thill-iron. Fig. 4 is a detached. plan view of that portion of my device at tached to the clip. Fig. 5 is a plan view of the combined bolt, head, and nut, which screws into the cylindrical. spindle shown in Fig. 4:. Fig. 7 is a perspective view of the leather packing, which goes into the eye of the thilliron and covers the sides of that iron with its flanges.

In the drawings, A represents the axle; B, the clip; (i, the head, permanently attached to the clip, and bearing on its inner surface the cylindrical. spindle, (represented by E in Fig. i.

1) represents the thill-iron, of which the eye K is shown in the detached view, Fig. 2.

H in Fig. 7 represents the packing, which is inserted in the eye K of the thill iron D; and I represents the flanges, which keep that packing firmly in place and cover and protect the rattling surfaces L of the thill-ircn from the head 0 on one side and the bolt-head F on the other, as shown in Fig. 3.

G and F in Fig. 5 represent the combined bolt, head, and nut made solidly in a single piece, which, after the thill-iron is sprung into its place on the spin'dleE, is screwed into the spindle at the point 0. (Represented in Fig. 4.)

To uncouple the thill-head it is only necessary to unscrew the bolt G by turning the nut F, and then to spring the thill-iron inward over the spindle E, as may be readily and quickly done. To couple the thill-head the operation is reversed.

Having thus described the constructionand operation of my device, whatl claim is 1. In a thill-coupling, the combination of a solid head, 0, and straight hollow cylindrical spindle E, attached to the clip, with a thill-iron,D,havingacorrespondingly-straight cylindrical opening, a spool-shaped packing, H, of leather, rubber, or similar substance, with flanges I, and a solid combined bolt, head,

and nut to be screwed into the, hollow of the spindle E, substantially as set forth.

2. The combination of a solid head-piece and straight hollow cylindrical spindle E, having a beveled point, so as to preserve a straight firm draft, and yet admit the springing over the straight spindle of a closely-packed thill-iron, D, whose sides are protected by a spool-shaped packing, H, with a solid combined bolt, head,

and nut, which does not receive the wear of the thill-iron, and might be lost without lessening the strength and safety of the coupling, all

substantially as set forth.
